Meet LoraPaper, A Weather Station That Runs On No Batteries!
https://www.electronics-lab.com/meet-lorapaper-weather-station-runs-no-batteries/
Whenever we have projects that require displaying human-readable information, we typically go with LEDs or different gadgets that draw lots of juice from the available power supply. Sometimes, this is fine, yet on the off chance that your power options are quite constrained, or you need something to be shown for quite a while, this […]
0 to 5V output Analog Hall Sensor for Foot Controller
https://www.electronics-lab.com/0-5v-output-analog-hall-sensor-foot-controller/
This project includes an analog Hall Effect sensor and an Op-Amp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range. Two configurations of the magnet and Hall sensors are analyzed. Trimmer Potentiometer PR2 provided to adjust the offset and PR1 […]
ESP32 LoRa Sensor Monitoring with Web Server (Long Range Communication)
https://www.electronics-lab.com/esp32-lora-sensor-monitoring-web-server-long-range-communication/
I’m a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32. The LoRa communication capacity of the board […]
